WSAA Product Appraisal 1615 6 3 THE PRODUCT The ANT range of valve spindle extensions incorporating lengths of 150, 225 and 300mm are suitable for operation on gate valves up to and including DN300.

6 WSAA Product Appraisal THE PRODUCT The ANT range of valve spindle extensions incorporating lengths of 150, 225 and 300mm are suitable for operation on gate valves up to and including DN300. The black coloured valve spindle extensions are manufactured from a high strength composite material using an injection moulding process. Traditionally valve extension spindles are manufactured by welding or pinning forged or cast end-pieces onto a tube or shaft. Where the components are not corrosion resistant to soil and ground water, they are required to be protected with a suitable coating. The integrity of any welding is considered to be critical in allaying any operator safety concerns. The ANT range of injection moulded spindle extensions provides the benefit of a single piece homogenous product with no joins or welds. It is lightweight with a high degree of dimensional accuracy and is impervious to soil and ground water corrosion. Each spindle extension is fitted with a M12 Grade 316 stainless steel bolt to allow retention on to the spindle cap. FIGURE 1 ANT VALVE EXTENSION SPINDLE The material utilised for this product is a high strength, high stiffness glass fibre reinforced engineering thermoplastic material with exceptional dimensional stability and low warpage. The products are covered by Registered Design No SCOPE OF THE APPRAIS AL This Appraisal considers 150, 225 and 300mm long ANT Valve Spindle Extensions for gate valves up to and including DN300, manufactured from a high strength composite material. 5 APPRAISAL CRITERIA 5.1 Quality Assurance Requirements The WSAA product appraisal network accepts Valve Spindle Extensions manufactured in compliance with AS/NZS :2011 Gate valves for waterworks purposes-metal seated and AS/NZS Gate valves for waterworks purposes-resilient seated.

Full specifications of the compound have been provided for this Appraisal on a commercial-in-confidence basis. Such information can only be provided to WSAA members with the express agreement of the applicant. The characteristics of the composite material include high stiffness and strength with exceptional dimensional stability and low warpage. Its maximum short term usage temperature is 1800 deg C. The end product is solid coloured, which means any scratches or marks will not affect the visible colour. The material is resistant to soil and ground water corrosion Dimensions AS/NZS 2638 specifies critical mating dimensions of the caps and keys to ensure compatibility of all components in the field. ANT has detailed the critical dimensions of their spindle extensions, in the type test report, to verify compliance Type Tests A strength test is specified in AS/NZS 2638 to ensure safe performance of valve spindle extensions in the field. The test requires the spindle extension to be fitted to a spindle cap and a torque applied until it reaches 1.25 times the minimum strength test torque of the maximum size valve it has been designed to operate.

WSAA Product Appraisal 1615 8 AS 2638.1 and AS/NZS 2638.

ANT has provided a copy of a report describing the test carried out on a 300mm long spindle extension at 1130Nm.

There were no visible signs of cracking, stress whitening, splitting or any damage or defect to the spindle extension.

8 WSAA Product Appraisal AS and AS/NZS both specify a minimum strength test torque for a DN300 gate valve as 900Nm, which equates to an applied test torque to the spindle extension of 1125Nm. ANT has provided a copy of a report describing the test carried out on a 300mm long spindle extension at 1130Nm. The test was conducted in-house by ANT and witnessed by Colin Paxman, Standards and Design Auditing Manager for South East Water.

9 WSAA Product Appraisal WATER AGENCY EXPERIENCE WITH THE PRODUCT OR FIELD TESTING REPORT Valve spindle extensions are considered standard products and installation trials were not required as part of this Appraisal. 12 OUTCOMES OF EXPERT PANEL PRODUCT REVIEW Q1. Is the material UV resistant? A1. In normal applications the valve spindle extensions are located in an air cavity below ground level, covered by a valve cover, with negligible exposure to UV radiation. Testing to ISO Methods of exposure to laboratory light sources Xenon-arc lamps indicates no change to tensile strength over 10 years with an exposure of 4.8 GJ/m2. Considering the thickness of the component, even if the surface was effected by constant UV radiation over many years, the physical properties would remain intact. Q2. The valve spindle extensions seem capable of stacking to provide additional extension lengths such as 375mm, 450mm, 525mm, 600mm, 750mm, 825mm, 900mm and so on. Is such stacking permitted? Is there any limit to the stacking? Has torque testing been carr ied out with stacked extensions? A2. The valve spindle extensions could be stacked to achieve additional heights. It has not been considered necessary to conduct torque tests for stacked extensions as each piece is able to withstand the necessary maximum applied torque. There is theoretically no limit to the stacking height, as the retention screws ensure the assembly does not vertically separate. The resistance to torque is provided by the cap to key fitment. 13 FUTURE WORKS No future works has been identified for this Appraisal. 14 DISCLAIMER This Product Appraisal Report (Report) is issued by the Water Services Association of Australia Limited on the understanding that: This Report applies to the product(s) as submitted.
